Abstract:

         For many people robot is a machine that imitates a human—like the androids in
Star Wars, Terminator and Star Trek: The Next Generation. However much these robots
capture our imagination, such robots still only inhabit Science Fiction. People still haven't
been able to give a robot enough 'common sense' to reliably interact with a dynamic
world. The type of robots that you will encounter most frequently are robots that do work
that is too dangerous, boring, onerous, or just plain nasty. Most of the robots in the world
are of this type. They can be found in auto, medical, manufacturing and space industries.
In fact, there are over a million of these types of robots working for us today. A study of
robotics means that students are actively engaged with all of these disciplines in a deeply
problem-posing problem-solving environment.

         Line follower is a machine that can follow a path. The path can be visible like a
black line on a white surface (or vice-versa) or it can be invisible like a magnetic field.
Sensing a line and maneuvering the robot to stay on course, while constantly correcting
wrong moves using feedback mechanism forms a simple yet effective closed loop
system. As a programmer you get an opportunity to ‘teach’ the robot how to follow the
line thus giving it a human-like property of responding to stimuli. The one more feature
in this application is picking and placing the object if detected.


The main heart of the hardware module is the microcontroller which is the programmable
IC. The programming language used for developing the software to the microcontroller is
Embedded/Assembly. The KEIL cross compiler is used to edit, compile and debug this
program. Micro Flash programmer is used for burning the developed code on Keil in to
the microcontroller Chip. Here in our application we are using AT89C51 microcontroller
which is Flash Programmable IC.AT represents the Atmel Corporation represents CMOS
technology is used for designing the IC. This IC is one of the versions of 8051

Practical applications of a line follower: Automated cars running on roads with
embedded magnets; guidance system for industrial robots moving on shop floor etc.
